I am pretty sure all att gs2s started out on kh7. So you must have changed it at some point to have been in kj1.

the modems on these phones are for cell, data, and gps reception only. They are independent of kernels and roms. Most custom packages do include a modem tho.

Modem performance seems to be regional and device specific so try out all three and see which one works best on your phone.

Wow, has anyone in the SF Bay Area been able to reliably get speeds much faster than 1.5Mbit down? I think the AT&T network here is just crap, and probably saturated with iPhone users. Please let me know if I am wrong, I've tried a few of these modems now....

[AT&T Samsung Galaxy S II SGH-I777] Simba501:
To the OP, this seems like a good idea to implement. We'd need everyone to chime in with performance and their location. The OP could provide data in the first post next to the modem informing others of where it's been reported to work well. Seems like a good idea.

[AT&T Samsung Galaxy S II SGH-I777] Peaster111:
Now that you mention it, I remember seeing that. Thanks for the suggestion. Let me see what I can come up with.
[AT&T Samsung Galaxy S II SGH-I777] slickie88:
^^^ agreed. Would love to see this.

The problem I'm having is finding a way to reliably test each of these modems. The only place I really have any time to test is when I'm at home (northeast Dallas) and at best I get 3 bars, but more often only 2. All of these modems performs pretty dismally at home and I suppose that has more to due with the poor signal strength. Other parts of town where I've done spot checks have given me decent results in speed tests, but it's difficult for me to say that any of these modems are clearly better than another.

Besides speed tests (Speetest.net app and speakeasy's web test), what are people using for modem evaluation? The OpenSignal app seemed promising for tracking tower locations and perhaps cluing me in on which towers are good/bad, but it doesn't seem to work reliably for me.

Best one for long island? Thanks in advance
[AT&T Samsung Galaxy S II SGH-I777] randrewm97:
ive run kj4 now for about a week and tested it with pretty linear results. i just switched to kk6 and my reception has increased by 1 bar in my apartment. its usually at 1 bar or no bars, now its either 2-1 bars.

my best results for kj4 was 1.84mbps down and 0.67mbps up and 134ms ping

my best results for kk6 was 2.03mbps down and 1.34mbps up and 153ms ping

the ping seemed a tiny bit better in every test but the up and down speeds were always better with kk6, plus the reception is better. so kk6 works best for me so far.

im in cincinnati, ohio
[AT&T Samsung Galaxy S II SGH-I777] 33t:
this might be completely obvious to some people, but it took me about three weeks to accidentally observe.

The damn server you choose on Speed Test can have about a 2-4 fold impact on your speeds. I was getting like 2.5 MAX, honestly more often <2. Then i just started trying a few different servers near my area and have found the on back to back testing one server will deliver me a speed of near 7 down and a different server 15 seconds later will deliver me speeds of around 2.

this whole download speed thing is sort of ridiculous when you consider that.

2 cents.

[AT&T Samsung Galaxy S II SGH-I777] slickie88:
Thanks, Peaster111.

Again, I'd like to hear people's thoughts how to they effectively test different modems. Speed tests are prone to a lot of variables that impact their results, so they have to be looked at for what they are. Would be nice to have a unified testing methodology or set of tools that we could use in order for this sort of thing to have any real meaning.
[AT&T Samsung Galaxy S II SGH-I777] Simba501:
Ideally, I would test during a low data traffic time.

The device should be placed on a hard surface, without touching it after starting the test (so signal strength isn't affected). An average of at least 3-5 tests should give a pretty good picture. A comparison between modems would require that the tests for all modems occur on the same day, in the same time frame, using the same measure (I use speakeasy), and in the same spot/location.

*For my college students and graduates, this is our attempt to control extraneous variables so we can make a valid conclusion that the observed differences are due to the different modems, and not something else :).

I've found my GPS performance to be consistent regardless of modem, but I suppose testing it would work the same way. Only this time, averaging the amount of time it takes to lock on.

Everyone's thoughts?

What type of ROM are you running? The modems are packaged two ways. One is for Samsung based ROMs and the other for CM7/MIUI ROMs. The update zip needs to be the same.

[AT&T Samsung Galaxy S II SGH-I777] slickie88:
I too have seen no difference in GPS lock times between any of the modems. 3-5 seconds to lock using the GPU Status app (with the "Show time to GPS fix" option enabled).

I've also seen very little difference in any of the modems in terms of speed test (multiples run one after the other using both Speedtest's app and Speakeasy's java tests) when I test here at home. The point this raises for me is that I'm testing one single tower amongst hundreds here in Dallas. Plenty of factors that will color my tests from any one location. LOS to the tower, a big-ass hawk nesting on the tower, the weather, something quirky with that given tower, etc.

Single location results are very limited in their usefulness when we're talking about compiling results for a region/city. Something that tracks RSSI as you run around town for a week would be ideal. Again, I've tried the OpenSignals app, but it doesn't seem to play nice with the i777.

Perhaps my poor results here at home with any of the modems are over emphasizing to me the role that individual towers can play in all of this. I do get markedly better download speeds in other parts of town, but again none of these modems are standing out as measurably better than the others by simply doing speed tests.

This is really misleading as the title makes it seems like it's our phone and they have a picture of our phone and not the skyrocket.

I didn't flash it, but I'm just posting as a heads up for people with our phone not to do it.

Thanks for the heads up... Hopefully folks will read and heed.

I flashed it before I read this. Do not try it! cwm restore got me back.

I'm not sure if it matters, but the checksum doesn't match when comparing the KH7 modem provided here and the one inside the stock KH7 firmware.

Interesting... do you have the checksum matching version? I don't know if it matters either, but I'd rather have the "checksum matching" version. Better to be safe... Can you upload it? I'll revise once I have it.

Thanks!
